means granted August 10, 1943.

A feature of the invention u for operating a feed foot in an orbitalpathA composed of straight lines which Join each otherfat substantiallyright angles. the path lbeing substantially rectangular.

As illustrated, horizontal and vertical movements are imparted to thefeed foot from a single crank, the nearly vertical movements of thecrank being .utilized to impart vertical movements to the feed foot. andthe nearly horizontal movements of the crank being utilized to imparthorizontal movements to the foot. Of course the crank, during its nearlyvertical movement. has some lateral or horizontal movement. Thesehorizontal movements, however, are absorbed by operating a toggle whilenear its straightened position so that. when vertical movement of thecrank is being utilized to move the feed foot. its attendant horizontalmovement is nulliiied and the feed foot moves in a substantiallyvertical path. Likewise, whencthe horizontal movement of the crank isbeing used to move the feed foot, the attendant slight `verticalmovement isnulliedby moving a toggle whilenearA `its straight positionandthe feed foot. moves ina substantially horizontal path. .c 4

The rotation of the crank may be `divided into four quadrants, the zeroor starting point being at the end of a radius which isat 45 degrees tothe verticalextending down and toward the right from the center aboutwhich the crankrmoves. The crank moves counterclockwise about itscenter, the 90degree point being at the endoi the radius extending upand to the right at 45 degrees to the vertical, and so on.

The Amovement of the crank is imparted to two mechanical systems, onecomprising three toggles and an angle lever for imparting vertical or upA system comprising two toggles and two angle,

and-down movements to the feed foot. the other levers for impartinghorizontal or to-and-fro movements to thefeed foot. These may bereierredl to briefly as the vertical and horizontal systems; As thecrank moves from zero to degrees. its vertical movement is utilized tomove the feed foot down by breaking one toggle and straightening the twoothers in the vertical system, the unwanted horizontal movement beingabsorbed by moving one of the toggles in the Vhorizontal system while itis nearits straightened position. -Asthe crank moves from 90 degrees todegrees, its horizontal movement is im- 'parted tothe feed foot bylbreaking one of the Vtoggles. ofthehorizontal system and straighten-.ing the other. the unwanted vertical movement beingabsorbed by slightmovement of the sti-aightene'cl toggles of the vertical system.

Asfthe crank moves from 180 degrees to 270 1degrees,"itsnvertioal'movement is utilized to move i the feed foot up bystraightening the first toggle in thefverticalsystem and breakingtheother two. theunwanted horizontal movement being absorbed by a slightmovement of a straightened toggle in the horizontal system.

As the crank movesfrom 270 degrees back to zero. its horizontal movementis utilized to move the feed foot leftward, while raised, to itsstarting point by breaking the straight toggle and straightening theother one. Lthe unwanted vertical movement being .absorbed by aslightmovement of the straight toggle in the vertical system. As a furtherfeature of-the invention, novel means is provided for imparting avariable straight feed movement to the feed foot whileit is raised sothat the strip may be fed more than the insole is fed to avoid unduetension on the strip and prevent distortion of the insole due toapplication of the strip thereto while under too much tension. Y

To this end, one arm of the angle lever by which heightwise movement isimparted to the feed foot carries a slide which is connected `to thefeed foot and movement of which is under control of a cam. During therightward movement of theieed foot while raised. that is, in the fourthquadrant of movement of the crank. the 'cam is operated to permit amovement oi' the slide which changes the length of the arm oi' the anglelever in a direction to effect further rightwise movement of the feedfoot. the caml immediately moving the slide back to restore theiarm toits initial length again.

The illustrated machine is provided with a depressible. yieldinglysustained, rotatable table on which the work is placed, an adjustableedge gage being provided for locating the work with respect to thestrip-applying means. The feed foot is positively operated to engage thework, depress the table, feed the work in a straight line, and then riseabruptly. During the upward movement of the feed foot a tucking foot isdepressed positively to press the inner flange of the ribbed stripagainst the insole. this tool having a component of movement outwardlyof the insole to enter closely into the angle between the rib and theinner flange.

To engage the outer flange of the ribbed strip, a presser foot isprovided which yields slightly heightwise as the table presses the workupwardly against the presser foot when the feed foot rises. This footfor pressing the outer flange of the strip is provided not only with asurface to engage the outer ange but also with a surface upwardly andinwardly inclined with respect to the insole for engaging the outer faceof the rib, and is further provided with a hook to extend over the topof the rib to assist in guiding it through the machine.

After the strip has been applied to the insole, it has to be severed,preferably between the feed foot and the tucking foot, leaving enough ofthe strip under the front part of the feed foot to permit its initialattachment to the next insole'. For this purpose, as a feature of theinvention, a power-operated, operator-controlled knife is provided, theknife being movable transversely to sever the strip and having anupturned end portion for severing the rib portion of the strip. Theknife is controlled by a knee lever which trips a clutch to causeoperation of the knife. Means is provided for stopping the machine inthat portion of its cycle where the feed foot and the tucking foot areseparated to permit the passage of the knife between them.

These and other features of the invention will be explained more fullyin connection with the accompanying drawings and will be pointed out inthe appended claims.

The illustrated machine may be utilized for applying a ribbed strip S,such as that shown in Fig. 7, to an insole I, as indicated in Figs. 9and l1. The machine (Figs. l, 3 and 4) has a base portion 20 standing onthe floor. A rearwardly extending casing 22 contains an electric motorconnected to a shaft 23 which (Fig. 4) carries a spiral gear 24 meshingwith a spiral gear 26 on a horizontal shaft 28 having end bearings 30supported by a housing 32 mounted in the base 20. The shaft 28 carries aspiral gear 34 meshing with a similar gear 35 on a hollow vertical shaft36 mounted for rotation in ball bearings 38 carried by a sleeve 40suitably supported in the housing 32. Inside the hollow shaft 36 is avertical shaft 42 shown in two parts (for convenience in assembling),the parts being connected by a coupling 43. Clamped to the upper end ofthe hollow shaft 36 is a coupling member 44 having upwardly projectinglugs 45, and clamped to the shaft 42 is a coupling member 46 havingdownwardly projecting lugs 41. Between the coupling members is a berdisk 48 having marginal notches to receive the lugs on both the couplingmembers whereby the shaft 42 is driven from the shaft 36. The upper partof the shaft 42`is journaled in a housing 49 and carries a spiral gear50 meshed with a similar gear 5l on a horizontal shaft 52 also journaledin the housing 49 and carrying a pulley 53 connected by a V-belt 54 to apulley 56 on a main shaft 58 (Fig. l2). This shaft is journaled in aframe 60 which is secured to the rear wall of a casing 6I, the casingbeing formed as part of the head frame 62 which is bolted at 63 (Fig. l)to the upper portion of a hollow neck 64 slidable vertically in theupper portion of the base 2U. The housing 49 is bolted at 65 (Fig. 4) toa depending portion 66 of the hollow neck 64 to which the head 62 issecured and which is movable vertically in the upper part of the base20. The neck 64 is grooved longitudinally at 68 and the groove isengaged by a headed pin 10 adjacent to which is a screw 12 the head ofwhich engages the head of the pin 'l0 to force it into the groove andhold the neck in vertically adjusted position. By loosening the collar46 the height of the machine head may be adjusted to suit the operatorwithout disturbing the driving connections of the motor to the shaft 58.

The insole is supported on a circular table mounted to rotate freely ona central stud 8| seated in the top of a table support 82 and supportedby ball bearings 84 between the table and the top of the table support82 which is arranged to move up and down in a bearing sleeve 88 formedin a bracket 81 fixed to the head frame 62. The table support 82 (Fig.15) is hollow and contains a compression spring 88 bearing at its upperend against the table support and at its lower end on a hanged disk 90the lower side of which is recessed to receive the upper end of a screw92 threaded through an arm '94 on a 5 bracket 95 secured at 96 tothesleeve 86. The screw 92 has a thumb head 93 by which it may be turned tovary .the initial tension of the spring 88 and hence the force by whichthe table is held up to press the insole against the operatinginstrumentalities. Upward movement of the table 80 in response to thespring 88 is adjustably limited by ascrew 98 (Fig. 3) threaded through asplit collar secured by screws |0| onl the lower end of the tablesupport, the upper end of the screw 90 engaging the fixed bearing sleeve86.

The table 80 is depressed by pressure on a treadle |02 (Fig. 4)fulcrumed on a shaft |03 and connected by an adjustable rod |04 to alever |06 at I 01 (Fig. 3). The lever is pivoted at |08 to the bracket95 and engages between its ends a roll ||0 on one of the screws |0|which hold the collar |00 to the table support 82 (Fig. 15). De-

an insole to be placed on the table and located by which may result indistortion or "strapping of the insole. When the tape is fed a littlefaster than the insole, the strip is fulled instead of stretched and,when so applied, the insole remains flat and undistorted. To meetdifferent conditions, the distance A--E, that is, the overfeed of thestrip, may be varied.

The mechanism by which the feed foot is operated is mostly enclosed inthe casing 6| (Fig. 3) which has a cover |42, the mechanism thereinbeing sprayed with oil by an oil pump.

The vertical movements A-B and C-D are imparted to the feed foot bymechanism shown in Fig. 5, the horizontal movements B-C and D-A areimparted to the feed foot by mechanism shown in Fig. 6, and the variableextra feed A--E and E-A by mechanism shown in Fig. 8.-

The mechanical system for imparting the upand-down or vertical movementsto the feed foot is shown in Fig. and diagrammatically in Fig. 16

i where this system is represented in full lines.

engagement with an edge gage (Fig. 9). The

it is held by a set screw ||6. By loosening the screws, the head 62 maybe adjusted up or down and the screws tightened. A compression spring||8 on the rod |04 between the extension ||4 and the frame 20 sustainsthe treadle and treadle rod.

The edge gage |20 (Fig. 9) and the mechanism for shifting it by means ofa handle |22 (Fig. 3) to vary the position of the insole with respect tothe strip-applying mechanism are all carried by a bracket |24 secured tothe table support 82 so that when the table is moved up or down the edgegage |20 goes with it. The edge gage and the mechanism for shifting itare more fully described in my prior patent referred to above.

A reel carrying an indefinite length of the ribbed strip S is placed ona supporting rod |25 (Fig. 1) carried by a bracket |26 which is fixed tothe casing 6| forming part of the head 62. The end of the strip ispassed through a guide loop |28 carried by the bracket |26 and thenthrough the feed foot of the machine indicated generally by thereference numeral |30 (Fig. 3)

which is mounted on a lever |32. A portion |34 of the feed footunderlies the strip and is provided with teeth |33 (Fig. 16) to engagethe insole and feed it. A portion |35 of the feed foot overlies the .twoflanges of the strip. Pivoted at |36 to the feed foot are two feedfingers |38, |39 urged counterclockwise by springs |40, one finger beinglocated over each flange of the strip S, the fingers being soconstructed and arranged that, when the feed foot moves to the right,the fingers I 38, |39 will slip over the strip and, when it is moved tothe left, the fingers grip the strip and feed it along.

The movement imparted to the feed fcot |30 is substantially as indicatedin the diagram in Fig. 2. Starting at A, the feed foot moves verticallyto B, then horizontally from B to C to feed the work, then verticallyfrom C to D, then horizontally back to A, and-beyond A to E, and back toA. The line B-C represents the feed movement imparted to the insole; thediagonal C-A` plus A-E represents the amount of feed imparted to thestrip which, of course, is more than that irnparted to the insole. Thepurpose of feeding the strip more than the insole is fed is to avoidapplying the strip while it is under too much tension.

is 42.937 inches between centers.

This diagram shows the relative dimensions of all the links, arms andlevers and the locations of their centers as they lie in the head of themachine, as seen from the front, except that coinciding 'arms in twoinstances are shown as slightly diverging for the sake of clearness.

i. Referring to Fig. 5, on the shaft 50 is a crank pin |50 located .625inch from the center of the shaft and carrying a connecting rod |52which The connecting rod |52 extends upwardly and is connected by a balljoint |54 to an arm |56 ilxedto a shaft |58. The joint or couplingemployed at |54 is' preferably of the type disclosed more fully in myprior Letters Patent of the United States No. 2,173,155, grantedSeptember 19, 1939. Each of the parts |52, |56 is provided with ahemispherical recess, a steel ball being held in the recesses by aspring clip |60 embracing the parts. This provides a pivotal connectionin which there ls no lost motion and one in which any wear isautomatically taken up by the spring clip. Wherever convenient, thistype of connection is used in the machine rand will be referred to inthis description as a ball joint. Also fixed to the shaft |58 is an arm|62 of the same length as the arm |56 and coinciding with it as seenfrom the front of the machine. The arm |62 is pivotally connected at |63to a link |64 the other end of which has a balljoint connection |66 to alink |68 pivoted loosely on a fixed shaft |10. A link |12 has aball-joint connection to both the link |64 and the link |68. As the arm|56 is oscillated by the crank |50, the arm |62 and the link |64 act .asa toggle, breaking and straightening of which swing the link |68 aboutthe shaft |10 and cause up-and-down movement of the link |12 which, withthe link |68, acts as a second toggle. The lower end of the link |12 hasa ball-joint connection |14 with an arm |16 projecting from a rocker |18mounted on a xed shaft |80. The arm |16 also has a ball-joint connectionto one end of a link |62 the other end of which has a ball-jointconnection |03 to an arm |84 fixed by a split clamp |86 to a sleeve |86on a shaft |90. The sleeve extends through the front of the casing 6|and has an arm |92 fixed thereto and in which is mounted a slide |94. Agroove is milled in the arm |92 to receive the slide which is held inplace by a plate |96 secured by screws |98 to the arm |92. The lever |32ls pivoted at |99 to the slide |94 and is held in its innermost orleftward position by a tension spring 200 one end of which is attachedto a pin 2,57s,esa

202 on the top of the lever |82 and the other to a fixed bracket 204(Fig. 3). Up-and-down movement of the link |12 as described impartsmovement to the rocker |18 about its shaft |80, and the link |82 impartsoscillating movement to the arm |84 on the sleeve |88. Hence the arm |82fixed to the sleeve |80 is oscillated to move the pivot |98 of the lever|82 and hence the feed foot |20 up and down. The timing is such that theup-and-down movements occur between the horizontal movements. the feedfoot moving substantially in a rectangular path.

. Referring to Fig. 16, it will be seen that, as the ami` that theconnecting rod 220,will break the crank pin |50 moves through the firstquadrant pin moves down in the third quadrant from 180 to 270, the footwill move up from C to D, straightening the toggle |82, |84 and breakingthe other two toggles in this system. The diag gram will be discussedfurther after the other mechanical systems for moving the foot have beenexplained.

Horizontal movements are imparted to the feed foot |80 by the mechanicalsystem shown in Fig. 8 and by short dash lines in' Fig.. 16. The crankpin |50 has a horizontal connecting rod 2 20 (Fig. 6) coupled by a balljoint 222 to an arm 224 integral with a sleeve 228 mounted to rockfreely on the shaft |58. The sleeve 228 has an integral arm 228 and, forconvenience.in machining, a member 280 is secured by screws 232 to thearm 220 to give it the same length as the arm 224, these armscoinciding, as seen from the front of the machine. The part 28,0 of thearm 228 is connected by a ball joint 284 to a link 288 which isconnected by a ball joint 238 to an arm 240 fixed to a rockshaft 242.The rockshaft has fixed thereto an arm 244 connected by a ball joint 248to a link 248 which is connected by a ball joint 250 to an arm 252 fixedto the shaft |90 which projects through the front of the casing 8| andcarries a downwardly extending arm 254 in the lower end of which is apin 258 held by a split clamp 258 in one end of a link 280, the otherend of which is fiat and is guided between vertical surfaces formed in ablock 28| secured by screws 282 to a bracket 284 mounted on the casing8| (Fig. 3). A bracket 288 (Fig. 6) on the link 280 embraces the lever|32, and a pin 288 pivots the lever to the bracket and to the link 280.

Regarding the pivot |98 of the lever |32 as fixed, it will be seen thatrotation of the crank |50 will oscillate the sleeve 228 on the shaft|58, thus breakingl and straightening the toggle formed by the arm 230and the link 238. Thus, thelfree end of the arm 240 fixed to therockshaft 242 will move up and down. causing the toggle 'formed by thearm 204 fixed to the shaft 242 and the link 248 to be straightened andbroken, thus causing oscillation of the arm 252 and hence of the arm 254since both are fixed to the rockshaft |80. Oscillation of the arm 254will, through the link 280, impart movements to the lever |32 about thepivot 99, causing the feed foot to move to and fro substantiallyhorizontally.

toggle 228, 238, thus moving the angle lever 240, 244 counterclockwiseand straightening the toggle 244, 248. This toggle when straightenedlifts the arm 252 fast w the shaft |80 and moves the armv 254 leftward.the link 280 then moving the lever |82 about the center |89 to impart'feed movement B-C (Fig. 2) to the feed foot |80. In the fourth quadrantfrom 270 to 0 thesemovementswill of course, be reversed. the feed footmoving from D to A of the diagram.

The relation between the vertical and horizontal systems will now beapparent from Figfl.

v As the crank pin |50 moves from 0 to 90 to lower the feed foot, itshorizontal movement, which is only the distance of the chord of aQO-degree arc to the circumference of its circle, is absorbed by movingthe joint 234 of the toggle 228,l 238 through that small distance whichdoes not appreciably aifect the length of the toggle which is then nearits straight position. lWhen the y.

crank pin |50 is moving down from 180 to 270 the toggle 244, 248 isstraight and the horizontal movement of the pin is absorbed or nulliedby a slight movement of the joint 248 of that toggle.

During movement of the pin |50 from 90 to 180 to produce the feedmovement of the foot |30, the toggle |82, |84 isbroken and the toggles|88, |12 and |18, |82 are straight so that the vertical movement of thepin through that arc will be absorbed by slight movement of the joints|88, |.-14.

During movement of the pin |50 from 270 to 0 to move the feed foot' fromD to A, the vertical movement of the pin will be nullified by slightmovement of the joint |83 of the toggle |82, |84 which is then straight.

In order to impart the extra feed movement (A-E) of the diagram (Fig. 2)to the feed foot to feed the strip more than the insole is fed, themechanism shown in Fig. 8 is provided. On the shaft |58 which isoscillated by the .upright connecting rod |52 is an arm 800 held to theshaft by a split clamp 302. The arm is connected by a link 804 to an arm808 fixed by a split clamp l308 to the shaft |10 which passes throughthe front of the casing 8| and has secured to it a segmental path cam 82 the path of which is engaged by a roll 8|4 on an arm 8|8 of abell-crank lever fulcrumed on a fixed shaft 3|8. The other arm 820 ofthe lever is slotted at 322 to receive a roll 324 the stud 828 of whichpasses through a slot 828 in an arm 330 of a lever having a fixedfulcrum on a shaft 382, the other arm 884 of the lever extending down atthe rear of the slide |94. The arm 334 is bored longitudinally toreceive a pin 388 extending upwardly from a block 838. The block has ahole at right angles to the pin 838 which is engaged by a pin 300 fixedto the slide |94 and passing through a slot in the rear face of the arm|92 into the hole. Thus, oscillation of the lever arm 334 will move theslide |94 lengthwise of the arm |92, the arcuate movement of the leverarm 384 being compensated for by sliding of the pin 888 in the arm'.

As the crank pin |50 moves up and dow'n, the arm 300 swings back andforth and imparts its movement to the arm 808 and the shaft |10 to thecam 3|2, the path of which is for the most part concentric with theshaft |10 but which. as it approaches the limit of its clockwisemovement. allows the roll 3 I4 to move slightly upward by engaging aportion 3|5 of the cam which is farther from its center, hencepermitting counterclockwise movement of the bell-crank 8|8,

9 320. "This movement swings the arms 320 and 330 to the right and thearm 334 to the left. causing leftwise movement of the slide |94 andhence of the upper pivot |99 of the feed-footcarrying lever |32, thislever now fulcruming counterclockwise on its pivot 268 and causing thefeed foot |30 to move to the right tothe point E of the diagram. Thetiming is such that the action of the cam 3|2 occurs during the upperhorizontal movement D-A of the feed foot, that is, in the lower quadrant(270-0), and the heightwise movement of the crank pin H50 in thatquadrant is utilized to move the cam 3m clockwise. enough to allow theroll 3M to engage the part 3|5 of the cam, for an instant and then tomove the cam back again to the position shown. This causes the feed footto move to the point E ofthe diagram and back to A, the counterclockwisemovement of the cam occurring as the crank pin rises from its lowestpoint to The position of the cam 8|2 on its shaft |10 to effect theoperation above described is rather critical.v Accordingly, the cam 3WFig. 8) is loose on its shaft |10 and is provided with a dependingportion 350. A split clamp 353 held tightly tothe shaft by a screw 350and preferably keyed thereto is provided with a depending portion 356corresponding to the portion 350 of the cam. By clamping these dependingportions temporarily together and adjusting them relatively to eachother. the proper position of the cam relatively to the shaft |10 may befound, whereupon the depending portion of the cam and the split clampare secured permanently together by screws 358.

In the diagram of Fig. 16 the mechanism just described is shown in longdash lines. As the crank pin |50 moves through the fourth quadrant from270 to 0 to give the feed foot its movement from D to A, there will be aslight vertical movement of the connecting rod |52 to and from itsextreme lower position. The arm 300 therefore moves slightly to theright and back again and, through the link 300, moves arm 300 and thecam 3|2 clockwise. causing the roll 3110 to move into the part 3|5 ofthe cam and back again. Thus, through the mechanism described, the slide|90 is moved to the left sufilciently to cause the feed foot fulcrumingon the center 000 to move to the point E of the diagram and back to A,this distance representing the amount the strip is fed more than thediagonal distance C--A which itself is more than the work is fed,

the work feed being represented by the line B-C. v

The cam IN2, being a path cam, positively actu-A ates the roll 3M. Thespring 200 serves to take.

up any lost motion in the joints connecting the lever |32 to the cam andnormally holds the cam roll 3|0 against the outer wall of the cam track.

" The amount of the strip feed A--E can be varied by adjusting the roll324 up or down in the slot 000 of the arm 320.

Means for pressing the inner flange F of the strip S is provided whichacts also to tuck the material of the strip sharply into the anglebetween the inner face of the rib and the inner flange F. As shown inFig. 9, the rocker |18 has an upwardly extending arm 310 connected by aball joint 312 to one end of a link 314, the other end of which isconnected by a ball joint 336 to an upright arm 318 ilxed to a rockshaft380. The shaft extends through the front wall of the casing 0i (Fig. .3)and has adjustably secured.

thereto a horizontal arm 382. A member 304 (Fig. 9) is pivoted on afixed shaft 3 mounted in a bracket 381 secured to the casing 8|. The`sion 390 to which is adjustably secured by a screw 396 a pressing andtucking foot 000 the lower face of which engages and presses the innerflange F of the strip S down upon the insole I and the rear face ofwhich is outwardly and upwardly inclined to enable its lower rear cornerto engage the strip material in the acute angle between the rib R andthe inner flange F. Since the tucking foot moves in a circular arcdetermined by the shaft 386, its up-and-down movement has a rearwardcomponent acting toward the rib and into the angle between the rib andthe flange.

Since the operating connections for the tucking foot 000 are positive.it is desirable to provide adjustment for the lower limit of itsmovement. Hence the arm 302 is made adjustable with respect to the shaft300. The shaft has an integral collar 002 and a reduced portion 000 thatextends through a hole in the arm 303. Screws 000 with conical ends(Fig. 10) are threaded through the arm 332. their conical ends enteringholes 003 in the collar 000 and each conical end bearing on one side ofits hole. For example, eachconical end may bear on the lower side of itshole; then, by turning one screw 000 out and the other in, the free endof the arm 300 will be moved up or down about the axis of the shaft 300.The screws 000 are secured in adjusted position by set nuts M0 and.after adjustment, the arm is securely fastened to the collar 003 byscrews 0|2 (Fig. 9) passing through slots in the arm 330 and threadedinto the collar 003.

The outer ange F' of the strip is laid by means best shown in Figs. 9and 15 and consists of a holddown or presser foot 020 adjustably securedat 02| to an arm 032 on a yoke 000 pivoted on short shafts 320, 331having bearings in the machine head 03'. The foot 000 has a surface 023(Fig. 11) which presses on the outer ange F' of the strip and a surface030 which extends up the outer wall of the rib R, the foot extendingover the upper edge of therib in the form of a hook 032. The hook servesas a guide for the rib but does not extend far enough to interfere withthe action of the tucklng foot 000.

The foot 030 has a slight upward yield (Fig. 15) to provide which thearm 322 has a rod 030 attached to it, the rod extending down through ahole in a web 030 of the bracket 01. On the rod. below the web is acompression spring 000 lighter than the table spring 08, and on the rodwithin the spring 000 is a sleeve 4M, the spring and sleeve being heldon the rod by a washer and nuts 002. The sleeve is shorter than thespring to permit a slight upward yield of the foot to maintain a lightpressure through the spring 040 on the outer flange F of the strip whenthe feed foot |30 has depressed the table and is feeding the insole.When the table 00 is lowered to remove the work, descent of the foot 030is limited by engagement of stop nuts 003, threaded on the rod 330, withthe web. When, during operation of the machine, the table 00 is allowedto rise, the sleeve 00| engages the web 438, thus limiting upwardmovement of the foot 420 against which the outer ange is then pressed bythe spring 00. At the same time, the tucking awaesa wheel 450 isconnected to and disconnected from the main shaft 58 (Fig. 12) by amultiple-disk clutch of known type. A Series of disks 452 is secured toahub portion 454 of the pulley to rotate therewith, and an alternateseries of disks 456 is connected to the shaft 58. A sleeve 458 splinedto the shaft is longitudinally movable thereon. and to vary itseffective length a knurled collar 468 is threaded on one end ofthe'sleeve and hasa reduced portion 48|, to press upon the disks 452,456. At the'other end of the sleeve is a similar collar 460 for engagingtwo series of disks similar to 452, 456, one series rotating with theshaft and the other series. alternating with the first. being secured toa sleeve 464 keyed at 466 in a member 468 secured by screws 410 to theframe 80. When the sleeve is moved to the left (Fig. 12) the disks 452.456 are pressed together and the pulley 56 drives the shaft 58. When thesleeve is moved to the right, the right-hand v disks are pressedtogether and the shaft is 4;

stopped.

The clutch is controlled by a treadle 480- (Fig. 4) fulcrumed on theshalt |08 like the treadle |02 and connected to a treadle rod 484 madeadjustable in the same manner as the rod |04, the treadle being raisedby a compression spring 485'located on the rod 484 between the base anda collar on the rod. The upper end of the treadle rod (Fig. 13) ispivoted at 488 to an arm 488 of an angle lever fulcrumed at 480 on thehead 80 and having a longer arm 482 on which is pivoted at 484 a blockarranged to move heightwise between projections 466 on a sliding yoke488. The yoke is splined at 500 to a horizontal shaft 502 havingbearings at its ends on the frame 60.

Extending upwardly from the yoke is an arm 504 carrying a roll 506 whichengages a cam 508. On the shaft 502 is splined and secured by a setscrew 5|0 a depending arm 5|2 which is connected by an adjustable link5|4 (Fig. 12) to a lower arm 5|6 of a lever fulcrumed at 5|8 on theframe 60. An upper arm 528 of the lever is in the form of a yoke to thearms of which are pivoted at 522 blocks 524 which slide in a peripheralgroove 528 in the sleeve 458. The link 5|4 is so adjusted that, when thehigh part of the cam 508 engages the roll 506, the lever 504, 5|2 willpull on the rod 5|4 and, through the lever 5|6, 820, move the sleeve 458to the right, applying pressure to the right-hand series of disks andstopping the machine.

To start the ma'chine, the treadle 488 is depressed to pull on the rod484 which turns the lever 488, 482 (Fig. 13) counterclockwise, causingthe yoke 488 to slide to the left on the shaft 502 and the roll 506 tomove of! the cam` 508, thus releasing pressure on the right-hand seriesof disks (Fig. 12).

To apply pressure to the left-hand series of disks and cause the shaft58 to be driven, the treadle rod 484 carries near its upper end a rollor stud 538 (Fig. 13) which is located between two blocks 532, 533adjustably held by screws 534 to an arm 536 (Fig. 12) of an angle leverfulcrumed at 538 on the frame 80 and having an upwardly extending arm540 which engages a' roll 542 mounted on the depending arm 5|2. Furtherpressure on the treadle acts through the lever 588, 540 to push the link5|4 in direction to move the sleeve 458 to the left and, by pressure onthe left-hand series of disks, to cause the shaft 58 to be driven. Uponrelease of the treadle 480 the compression spring 485 reacts to move theroll 508 in position to be engaged by the cam 508 the projection ofwhich engages the roll and applies pressure to thie right-hand disks tostop the shaft 58.

The strip S is usually applied to the insole I by starting'at one end ofthe breast line on one side of the insole and applying the strip alongthe shank and around the forepart and shank to the other end of thebreast line where the strip must be severed.

Operator-controlled power-operated means is provided for severing thestrip operable only after the shaft 58 has been stopped in that portionof its revolution when the vfeed foot |30 is widely separated from thetucking foot 400 so that a horizontally moving knife having a cuttingedge on its lower side may move across the strip between these feet. Aknife 550 (Figs. 9 and 15) located in a vertical plane has its loweredge sharpened, the outer portion of its edge extending upwardly at anobtuse angle vto about the height of the rib R. The longer portion ofits edge is at an angle of about 2 to the horizontal to cause thecutting to be done pricipally by the corner where the two portions ofthe edge meet at the obtuse angle. The blade 550 is ixedly mounted byscrews 552 in the split end of a shaft 554. Mounted for verticaladjustment on the arm 422 is a block 56 (Figs. 9) the block having avertical rib 558 set into a corresponding groove in the arm 422 andbeing held in adjusted position by screws 580 (Fig. l5) The block 556(Fig. 9) is bored longitudinally slidingly to receive the shaft 554,there' being a slot along the lower side of thebore to permit the knifeedge to extend slightly below the lower face of the block 558. Holes 562are provided in the block to aiTord access to the screws 552 which holdthe knife in the shaft.

By loosening the screws 560 the block 558 guided by the rib 558 may beadjusted heightwise so that the obtuse angle between the cutting edgesof the knife 550 will be in a plane the thickness of the flange F belowthe surface 428 of the foot 420 which rests upon the flange and againstwhich the insole is held by the table spring 88. Thus, when the knife550 is moved horizontally outward, it will sever the strip withoutcutting into the insole.

To facilitate fine adjustment of the knife vertically, the block 558 isprovdedwlth a horizontal slot 563 (Fig. 15) which is engaged by aneccentric stud on the head of a screw 564, the screw head beingcountersunk in the arm 422 and the screw extending through the arm andbeing provided with a screw-driver slot in its end and with a set nut565 on its outer threaded portion. By loosening the nut 565 and thescrews 560, the block 556, and hence the knife, may be adjustedvertically relatively to the arm 422 by turning the screw 564 with ascrew driver, the holes in the arm 422 through which the screws 60extend being elongated vertically to permit such relative adjustment.

To operate the knife, the shaft 554 (Fig. l5) is connected by anadjustable link 568 to an arm 561 of an angle lever fulcrumed at 568 ona bracket 569 in the head frame 62. The other arm 610 of the angle leveris connected to( a vertical rod 512 (Fig. 4) secured at 514 in the upperend of an extension 516 which is pivoted to an arm 518 fixed to a shaft580 journaled in a bracket 58| secured to the housing 32. Another arm552 fixed to the shaft 500 is linked by a ball joint 583 to the upperend of a connecting rod 684 which has a universal joint connection to acrank pin 586 (Fig. 14).

The crank pin is eccentrically fixed in the end of a cylindrical member606 having a bushed bearing ln a plate 590 fixed by screws 502 to thehousing 32 (Fig. 4). The 4member 586 has a larger portion formed as acam 594 (Fig. 14). Against the right-hand face of the larger portion ofthe member is a bearing ring 636 which is urged to the left by hollowplungers 593 containing springs 600. The member 580 is bored and bushedto receive a shaft 602 which is pinned to a worm wheel 604 continuouslydriven when the shaft 23 is rotating by a wenn 606 on the shaft (Fig.4).

The adjacent faces of the worm wheel 644 (Fig. 14) and of the cammedportion of the member 580 are each provided with, a plurality of dogs600 which are normally held out of engagement by a pin 54,0 engaging thecam 534. When the pin is lifted the springs 600 push the dogs 603 intoengagement, causing the member 444 to be rotated and the crank pin 506to operate the knife 550 through the connections described.

The end thrust of the shaft 602 (Fig. 14) is taken by a sleeve 612 inwhich the shaft rotates. The sleeve can turn and move endwise in.acylindrical bore in a member 614 which is suitably secured to thehousing 32. The outer portion of the member is threaded to the outerportion of the sleeve 612 and has a split clamp 414 by which the sleeveis held against rotation.v

en this is loosened the sleeve 612 may be turned by an exposed knurledhead 614 outside oi which a collar 620 is pinned to the shaft 404.Turning of the sleeve adjusts it and hence the shaft longitudinally toobtain the proper relation between the worm 006 and the worm wheel 604,this adjustment being maintained by the split clamp 616. Suitable oilpassages are provided as shown.

The pin 610 is mounted for vertical movement in the bracket 573 securedto the top of the housing 32 and has a grooved head 624 at its upperend, the groove of which is engaged by a pin or roll 626 on a lever 620fulcrumed at 634 on the bracket 519. The lever 620 is pivotallyconnected to a rod 632 made extensible like the rod |04 and leading upto a point at the rear of the lower end of the table support where it isjointed to an arm 634 (Figs. 1 and 15) on a rockshaft 636 extending fromfront to rear of the machine (Fig. 13) where a member having two arms630, 640 is fixed to it, these arms and the arm 634 being held at thelimit of their clockwise rotation with the shaft 636 by a helicaltorsion spring 64| on` the shaft 636 (Fig. l5). The arm 638 (Fig. 13) isin the path of a screw 444 threaded through an arm 644 (Fig. 1) of anangle lever fulcrumed to the machine head at 644 and having an arm 646extending down through a slot in a work table 640. The lower end of thearm B46 has a knee pad 650 secured to it, the pad being adjustableheightwise and about a vertical axis. The lever 646 is held in theposition shown by a tension spring 662 (Fig.

14 13) connected at one end to the lever and at the other end to themachine head. Pressure on the pad 650 to swing the lever causes thescrew 642'to depress the arm 638 and turn the shaft 606 in a directionto lift the arm 634, the rod 632, the lever 623 (Fig. 14) and the pin6I0, thusv .n therefore be disastrous to operate the knife while themachine is in operation. To prevent such operation of the knife, theclutch treadle rod 404 passes through an ear 653 (Fig. 13) pivoted to anarm 454 of a lever having a fixed f-ulcrum at 646 on a bracket 634. Theend of the other arm 650 of the lever is adjacent to the arm 640 on theshaft 636. On the treadle rod 404 collars 660 are secured one above andone below the ear 643. When the treadle rod is depressed to start themachine, the arm 654 moves clockwise and the end of the arm passes bythe end of the arm 640, thus preventing rotation of the shaft 636 in thedirection to cause operation of the knife 640 while the machine isrunning to apply the strip.

Furthermore, when the .knife is being operated, it should be impossible,for safetys sake, to operate the strip-applying mechanism. Accordingly,as shown in Fig. 13, when the knife clutch has been tripped, the arm 640assumes the positionshown in dotted lines against a stop pin 662, inwhich position it lies above the arm 650 and hence prevents depressionof the treadle rod 404 to cause operation of the strip-applyingmechanism. Thus, the operation of the two clutches is mutually exclusivesince neither can be operated when the other is in, operation.

There is also a possibility that the clutch on the main shaft 50 mightget out of adjustment to such an extent that it failed to stop the shaftin that region of its rotation in which the knife 450 could be safelyoperated or the shaft.. might be turned by hand to such a position. Toprevent operation of the knife under such conditions, the web of thehand wheel 450 (Fig. 12) is provided with an arcuate groove 664 extend--ing through an arc representing that portion of the rotation of theWheel in which the knife 550 can be safely operated. that is, while thetucking foot 400 and the feed foot 430 are most widely separated.

A feeler rod 665 is mounted for limited endwise movement in the frame 60and has a grooved head 660 'at its right-hand end the groove of which isengaged by the upper end of an arm 610 of an angle lever pivoted on theshaft 518 and having an arm 642 connected by a link 614 to an ear 616pivoted at 670 to the arm 638. If the machine has stopped with thegroove 664 opposite the feeler rod 666 it can enter the groove and theknee lever 646 can be operated, b ut if the machine has stopped with anungrooved part of the hand wheel opposite the feeler rod longitudinalmovement of the rod is prevented and hence the knee, lever cannot turnthe arm 630 to raise the rod 532 to trip the knife clutch.

It will be noted that the rotating and oscillating parts r'e providedwith counterweights to minimize vibration; for example (Fig. 6), theshaft il has a counterweight 680 equivalent to the weight of the crankpin and a large part of the connecting rods |52, 220, the sleeve 226 iscounterweighted at 682 to counterbalance the arms 224, 228 and 230 and aportion of the connected parts 236, 220, and other oscillating parts aresimilarly counterweighted as shown.

A motor-controlling switch 884 (Fig. l) is located on the base 20. Alamp 688 controlled by a switch 688 is attached to the bracket |26 andis arranged to throw light upon the work at the operating point. Aremovable shell 690 is provided to cover the mechanism outside of thefront wall of the casing 6l, and a hinged cover 692 protects the clutchat the rear of the machine.
